A. A. Adebesin, O. T. Saromi, N. A. Amusa, S. O. Fagade
Journal of Food Technology in Africa , 2001,
Abstract: The microbial quality of roasted groundnut , Kulikuli, Yaji and Dankwa hawked in three major areas in Bauchi, Northeastern Nigeria was determined. The microbial load of the product from from each location differs, while that of bacteria isolates ranges from 1.16±0.32x105 to 5.92±0.59 x105 colony forming units/gram (cfu/g), the fungal count ranges from 1.91±0.32 x104 to 8.60±0.22x104 cfu/g of the samples. Roasted groundnut had the highest count of micro-organisms followed by Kulikuli, then Yaji and Dankwa had the least. The dominant mold in these products was Aspergillus niger, Rhizopus Stolonifer and A. flavus while the other associated fungi includes Penicillum citrinum, Mucor spp. and Macrophomina phaseolina. The bacterial isolates found associated with these groundnut products include Staphylococcus aureus, S. aureginosa, Micrococcus spp. and Bacillus cereus.

On the Application of Bootstrap Method to Stationary Time Series Process  [PDF]
T. O. Olatayo
American Journal of Computational Mathematics (AJCM) , 2013, DOI: 10.4236/ajcm.2013.31010
Abstract:

This article introduces a resampling procedure called the truncated geometric bootstrap method for stationary time series process. This procedure is based on resampling blocks of random length, where the length of each blocks has a truncated geometric distribution and capable of determining the probability p and number of block b. Special attention is given to problems with dependent data, and application with real data was carried out. Autoregressive model was fitted and the choice of order determined by Akaike Information Criterion (AIC) and Bayesian Information Criterion (BIC). The normality test was carried out on the residual variance of the fitted model using Jargue-Bera statistics, and the best model was determined based on root mean square error \"\" of the forecasting values. The bootstrap method gives a better and a reliable model for predictive purposes. All the models for the different block sizes are good. They preserve and maintain stationary data structure of the process and are reliable for predictive purposes, confirming the efficiency of the proposed method.

Truncated Geometric Bootstrap Method for Time Series Stationary Process  [PDF]
T. O. Olatayo
Applied Mathematics (AM) , 2014, DOI: 10.4236/am.2014.513199
Abstract: This paper introduced a bootstrap method called truncated geometric bootstrap method for time series stationary process. We estimate the parameters of a geometric distribution which has been truncated as a probability model for the bootstrap algorithm. This probability model was used in resampling blocks of random length, where the length of each blocks has a truncated geometric distribution. The method was able to determine the block sizes b and probability p attached to its random selections. The mean and variance were estimated for the truncated geometric distribution and the bootstrap algorithm developed based on the proposed probability model.
Rethinking Environmental Law Enforcement in Nigeria  [PDF]
Hakeem Ijaiya, O. T. Joseph
Beijing Law Review (BLR) , 2014, DOI: 10.4236/blr.2014.54029
Abstract: Environmental degradation has continued to generate unpleasant challenges for health and economic development in Nigeria. Some of these problems include deforestation, pollution, global warming and improper pesticides. Despite environmental laws and policies targeted at amelio-rating these problems, the situation in Nigeria seems degenerating owing to the fact that these laws are not effectively enforced. This paper analyzes the use of environmental laws by different enforcement agencies in Nigeria, the methods of enforcement these agencies invoke, and the challenges they face in enforcing the relevant laws. These challenges include low-level constitutional provision for environmental protection, roles and conflicts in environmental management, undue adherence to legalism by the courts and absence of mandatory disclosure of information. Thus, the legislative objectives remain unachieved because enforcement is superficial; excessive time exists between non-compliance and enforcement; available punishment for non-compliance is inadequate; injured parties are not properly compensated; and some environmental crimes receive administrative instead of remedial measures or criminal punishments. The study advocates for the encouragement of private and public interest litigation, creation of procedure for enhancing public participation in Nigerian environmental protection, creation of environmental emergencies and establishment of environmental courts.
Empirical Determination of the Tolerable Sample Size for Ols Estimator in the Presence of Multicollinearity (ρ)  [PDF]
O. O. Alabi, T. O. Olatayo, F. R. Afolabi
Applied Mathematics (AM) , 2014, DOI: 10.4236/am.2014.513180
Abstract:

This paper investigates the tolerable sample size needed for Ordinary Least Square (OLS) Estimator to be used when there is presence of Multicollinearity among the exogenous variables of a linear regression model. A regression model with constant term (β0) and two independent variables (with β1 and β2 as their respective regression coefficients) that exhibit multicollinearity was considered. A Monte Carlo study of 1000 trials was conducted at eight levels of multicollinearity (0, 0.25, 0.5, 0.7, 0.75, 0.8, 0.9 and 0.99) and sample sizes (10, 20, 40, 80, 100, 150, 250 and 500). At each specification, the true regression coefficients were set at unity while 1.5, 2.0 and 2.5 were taken as the hypothesized value. The power value rate was obtained at every multicollinearity level for the aforementioned sample sizes. Therefore, whether the hypothesized values highly depart from the true values or not once the multicollinearity level is very high (i.e. 0.99), the sample size needed to work with in order to have an error free estimation or the inference result must be greater than five hundred.

Journal of Building Construction and Planning Research (JBCPR) , 2018, DOI: 10.4236/jbcpr.2018.64021
Abstract: Air conditioning design has become an interesting aspect of human life with the aim of seeking environmental comfort for indoor spaces. Analytical work involves in the design of air-conditioning system is often time consuming and laborious. This work therefore aims at developing a visual interactive computer package for the design of air conditioning system using the international conference centre, University of Ibadan, Nigeria as a case study. Procedures for calculating heat gain through various building components were discussed in detail. Cooling load analysis was carried out using standard cooling load equations obtained from the American Society of Heating, Refrigeration and Air conditioning Engineers (ASHRAE) handbook. A computer program was developed using java programming language to compute the total cooling load in the building. The result from the computer program was obtained within a very short period of time when compared with that of the manual one. The cooling load of the building obtained was 3,194,414 btu/hr; a visual interactive computer package for the design of air conditioning system has been developed and tested positively; hence can be used to design air conditioning system for any building.

Abstract: Death of infants from diarrhoea is a common occurrence in sub-Saharan Africa. This is attributed to unhygienic practices which aid the proliferation of diarrhoea-causing microorganisms. Among these microorganisms, Cam- pylobacter species have been reported as one of the causal agents, Campylobacter spp. are human intestinal pathogens of global importance and their pathogenicity mechanisms are not well understood. This study was designed to investigate the molecular characterisation of Campylobacter gotten from cultural methods in Osun State. Campylobacters isolated were biochemically characterized and biotyped. Confirmation of Campylobacter was done using flaA gene, hippuricase O for Campylobacter jejuni and aspartokinase gene for Campylobacter coli and single locus sequencing glnA gene were performed by PCR. Twenty five samples were amplified by PCR out of 57 Campylobacter strains that were positive for cultural methods from 815 stool samples with diarrhoea and 100 stool samples without diarrhoea. No Campylobacter was isolated from stools of children in the control group. Twenty-five isolates comprising of 18 Campylobater jejuni and 7 C. coli were identified. The nucleotide sequence of the gln A for all the isolated Campylobacter spp. showed 91.0% similarity with the ones in the GenBank. The C. jejuni was classified into biotypes I (44.4%) and II (55.6%) and all C. coli were of biotype I.
